[0002] In the process of manufacturing steel box girders in sections, in order to ensure manufacturing accuracy, it is usually necessary to use an assembly jig for positioning and support. However, existing assembly jigs often have fixed structures and cannot be flexibly adjusted according to actual needs, resulting in poor use effects and failure to meet the needs of high-precision manufacturing. Therefore, how to provide a flexible assembly jig for manufacturing steel box girders in sections has become a problem that needs to be solved urgently. Utility Model Content

[0003] In order to facilitate the adjustment of the jig size, the present application provides an adjustable assembly jig for manufacturing steel box beam sections.

[0004] The adjustable assembly jig for segmented manufacturing of steel box beams provided in this application adopts the following technical solution:

[0005] An adjustable assembly jig for manufacturing steel box beam sections comprises a base plate, wherein two groups of oppositely arranged piles are provided on the upper side of the base plate, and each group of the piles is evenly and spacedly distributed along the same vertical plane, each of the piles is arranged in one-to-one correspondence with the two groups of the piles, the upper ends of the two corresponding piles are connected to the same cross arm, and the two adjacent piles in the same group are connected to the same diagonal brace, the lower end of each pile is slidably connected to the base plate along the arrangement direction of the piles in the same group, and the end of each diagonal brace is slidably connected to the pile along the length direction of the connected pile.

[0006] By adopting the above technical solution, when the size of the mold needs to be adjusted, the inclination angles between the multiple diagonal braces are adjusted, so that the diagonal braces drive the connected piles to move when the inclination angles change, thereby achieving adjustment of the relative positions between the multiple piles, thereby reducing the phenomenon that the mold is difficult to apply to different scenarios due to the fixed size of the mold.

[0007] Optionally, each group of the piles is connected to a distance adjustment component, and the distance adjustment component is used to adjust the distance between the ends of the diagonal braces connected to the same pile.

[0008] By adopting the above technical solution and setting the distance adjustment component, the phenomenon that the staff adjusts the inclination angle of the diagonal support inconsistently, causing uneven gaps between the columns and affecting the bearing capacity of the tire is reduced.

[0009] Optionally, the distance adjusting assembly includes multiple connecting blocks, each of which is arranged on one side of a pile connected to the two ends of the diagonal struts and corresponds to the ends of the diagonal struts one by one, each of the connecting blocks is rotatably connected to the corresponding end of the diagonal strut, and the two connecting blocks connected to the same pile are penetrated and threadedly connected with the same bidirectional screw.

[0010] By adopting the above technical solution, when the gap between the piles needs to be adjusted, the bidirectional screw is rotated, and the bidirectional screw drives the two connected blocks to move relative to each other, so that the two connecting blocks drive the connected diagonal brace ends to move, thereby realizing the adjustment of the inclination angle of the diagonal brace.

[0011] Optionally, a pitch-adjusting gear is fixedly connected to the middle position of each bidirectional lead screw, a driving gear is meshed on one side of each pitch-adjusting gear, and a driving motor is fixedly connected to one side of each driving gear.

[0012] By adopting the above technical solution, the driving motor is turned on to drive the driving gear to rotate, and the driving gear drives the pitch adjusting gear to rotate during the rotation process, and the pitch adjusting gear drives the bidirectional lead screw to rotate during the rotation process, thereby reducing the trouble of the staff in rotating the bidirectional lead screw.

[0013] Optionally, the plurality of drive motors in each group of the pitch adjustment components are arranged in series.

[0014] By adopting the above technical solution, by connecting multiple drive motors in series, the multiple drive motors can rotate simultaneously to adjust the angle of the diagonal brace, so that the diagonal brace can maintain the same inclination angle and drive the connected piles to move the same distance, thereby keeping the gaps between the multiple piles the same.

[0015] Optionally, each group of the stakes is connected to a limiting assembly, and each group of the limiting assembly is used to limit the positions of the multiple connected stakes.

[0016] By adopting the above technical solution and setting the limit assembly, the problem of difficulty in stably supporting the steel box girder due to changes in the position of the piles during use is reduced.

[0017] Optionally, the limiting assembly includes a limiting tooth block fixedly connected to the lower end of the pile, and the lower sides of multiple limiting tooth blocks in the same group are provided with limiting tooth plates that can engage with the multiple limiting tooth blocks, each of the limiting tooth plates is inserted into the interior of the base plate and slidably connected to the inner wall of the base plate, and each of the limiting tooth plates is fixedly connected to a side away from the adjacent multiple limiting tooth blocks with multiple pressure springs for driving the limiting tooth plate to move toward the direction close to the adjacent limiting tooth blocks.

[0018] By adopting the above technical solution, the position of the pile can be limited by setting a limit tooth block and engaging it with the fiber tooth plate, and the pressure spring can be set so that after the pile is moved, the distance adjusting tooth plate can move towards the limit tooth block under the drive of the pressure spring, thereby limiting the position of the pile.

[0019] Optionally, a positioning block is fixedly connected to one end of the upper side of the cross arm located at the end.

[0020] By adopting the above technical solution and setting the positioning blocks, the trouble of workers in positioning the first plate during the process of placing the steel box girder is reduced.

[0021] In summary, the present application includes at least one of the following beneficial technical effects:

[0028] The following is combined with Figure 1 -Attached Figure 2 This application is described in further detail.

[0029] The present application embodiment discloses an adjustable assembly jig for manufacturing steel box beam sections, referring to Figure 1 and Figure 2, comprising a base plate 1, the upper side wall of the base plate 1 being arranged horizontally. Two groups of multiple piles 2 arranged opposite to each other are arranged on the upper side of the base plate 1, each group of piles 2 is arranged with five piles and the five piles 2 in the same group are evenly spaced and distributed in the same vertical plane. Two slide grooves 11 are provided on the upper surface of the base plate 1, the two slide grooves 11 are arranged one by one with the two groups of piles 2 and each slide groove 11 is provided at the lower side of the corresponding pile 2, the length direction of each slide groove 11 is the same as the arrangement direction of the corresponding piles 2 in the same group, and the lower end of each pile 2 is plugged into the corresponding slide groove 11 and is slidably connected with the slide groove 11.

[0030] The two groups of piles 2 are arranged in one-to-one correspondence, and the upper ends of the two corresponding piles 2 are connected to the cross arms 3 arranged at the same level.

[0031] An inclined brace 4 is provided between two adjacent piles 2 in the same group, each inclined brace 4 is arranged obliquely, and multiple inclined braces 4 in the same group are arranged in parallel. A connecting rod 41 is fixedly connected to the end of each inclined brace 4, and each connecting rod 41 is inserted into the adjacent pile 2 and slidably connected to the inserted pile 2 along the length direction of the pile 2.

[0032] By setting the piles 2 and the cross arms 3, the support process of the steel box girder can be realized. When the size of the jig needs to be changed, it is only necessary to move a plurality of cross braces so that the cross braces drive the piles 2 to move inside the inserted slide groove 11, thereby realizing the adjustment of the size of the jig, so that the jig can be applied to jigs of various sizes.

[0033] A positioning block 31 is fixedly connected to one end of the upper side of the cross arm 3 located at one side of the base plate 1 .

[0034] The positioning block 31 can be provided to facilitate the positioning process of the first plate.

[0035] Each group of piles 2 is connected to a distance adjustment component 5, and the distance adjustment component 5 is used to adjust the inclination angle of the diagonal support 4.

[0036] By providing the distance adjustment component 5, when the size of the mold needs to be adjusted, the inclination angle of the diagonal support 4 is adjusted through the distance adjustment component 5, so that the diagonal support 4 can drive the connected pile 2 to move, thereby achieving the adjustment of the size of the mold.

[0037] The distance adjustment assembly 5 includes a plurality of connecting blocks 51. In this embodiment, the number of connecting blocks 51 in each group of distance adjustment assemblies 5 is six. Two connecting blocks 51 are connected to the three middle piles 2 in each group of piles 2. Two connecting blocks 51 are provided on one side of each pile 2 connected to two connecting rods 41, and the two connecting blocks 51 are arranged one-to-one with the two connecting rods 41. Each connecting block 51 is rotatably connected to one end of the corresponding connecting rod 41 that penetrates the connected pile 2. The two connecting blocks 51 connected to the same pile 2 are penetrated and threadedly connected with the same bidirectional lead screw 52, ​​and each bidirectional lead screw 52 is arranged vertically.

[0038] A pitch-adjusting gear 53 is fixedly sleeved in the middle of each bidirectional lead screw 52, ​​a driving gear 54 is meshed on one side of each pitch-adjusting gear 53, and a driving motor 55 is fixedly connected on one side of each driving gear 54. Each driving motor 55 is fixedly connected to an adjacent pile 2. Multiple driving motors 55 in the same group are electrically connected in series.

[0039] When it is necessary to adjust the spacing between multiple piles 2 in the same group, multiple driving motors 55 are started, and each driving motor 55 drives the connected driving gear 54 to rotate. During the rotation, each driving gear 54 drives the meshing spacing gear 53 to rotate. During the rotation, each spacing gear 53 drives the connected bidirectional lead screw 52 to rotate. During the rotation, each bidirectional lead screw 52 drives the two connected connecting blocks 51 to move relative to each other, thereby changing the inclination angles of the multiple diagonal struts 4 connected to the piles 2 in the same group, and then realizing the relative position movement of the multiple piles 2 in the same group.

[0040] Each group of piles 2 is connected to a limiting assembly 6 , and the limiting assembly 6 is used to limit the position of the piles 2 .

[0041] By providing the limiting assembly 6, the position of the pile 2 can be limited during actual use, so that the jig can stably support the steel box girder.

[0042] The limiting assembly 6 includes a limiting tooth block 61 fixedly connected to one end of each stake 2 inserted in the slide 11, and a limiting tooth plate 62 located at the lower side of the plurality of limiting tooth blocks 61 is also provided inside the slide 11, and the teeth of the limiting tooth plate 62 are arranged upward and can be engaged with the plurality of limiting tooth blocks 61 located at the upper side. Each limiting tooth plate 62 is located inside the slide 11 and is slidably connected to the groove wall of the slide 11 in the vertical direction. A plurality of pressure springs 63 are fixedly connected between the lower side of each limiting tooth plate 62 and the bottom wall of the slide 11. The end of each limiting tooth plate 62 passes through the base plate 1 and is fixedly connected to a pressure block 64.

[0043] When the position between the piles 2 needs to be adjusted, the two pressure blocks 64 at the end of each limit tooth plate 62 are pressed downward to drive the limit tooth plate 62 to move downward, so that the limit tooth plate 62 is no longer engaged with the adjacent limit tooth block 61, so that the pile 2 can be moved under the drive of multiple drive motors 55. After the movement is completed, the pressure block 64 is released, so that the limit tooth plate 62 can be engaged with the adjacent limit tooth block 61 under the drive of the pressure spring 63, thereby realizing the limitation of the position of the limit tooth block 61 and the connected pile 2.

[0044] The implementation principle of the adjustable assembly jig for segmented manufacturing of a steel box girder in an embodiment of the present application is as follows: when the gap between the piles 2 needs to be adjusted, the limit tooth plate 62 is moved downward so that the limit tooth plate 62 is no longer engaged with the adjacent multiple limit tooth blocks 61.

[0045] Then, multiple driving motors 55 are started, and multiple driving motors 55 drive the piles 2 to move, thereby adjusting the size of the mold. Then, the limiting tooth plate 62 is driven by the pressure spring 63 to engage with the adjacent multiple limiting tooth blocks 61, thereby limiting the positions of the multiple piles 2.

[0046] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
